Flood Watch
Issued: 11:35 AM May. 15, 2026 – National Weather Service
* WHAT...Flash flooding caused by excessive rainfall is possible. * WHERE...Niihau, Kauai, Oahu, Molokai, Lanai, Kahoolawe, and Maui. * WHEN...Through this afternoon. * IMPACTS...Flood prone roads and other low lying areas may be closed due to elevated runoff and overflowing streams. Urban areas may receive more significant flooding and property damage due to rapid runoff. * ADDITIONAL DETAILS... - An unseasonably cold upper level low moving into the Hawaiian Islands from the north will produce periods of heavy showers across the island chain today. The center of the low will settle in over Kauai around noon HST, the low will then weaken and drift slowly eastward tonight. Unstable conditions within this upper low will likely produce periods of thunderstorms and heavy showers, potentially leading to flash flooding conditions in some areas. This Flood Watch may need to be extended into the overnight hours for some counties. PRECAUTIONARY/PREPAREDNESS ACTIONS... You should monitor later forecasts and be prepared to take action should Flash Flood Warnings be issued. &&
Special Weather Statement
Issued: 3:08 AM May. 15, 2026 – National Weather Service
...UNSEASONABLE UPPER LOW TO BRING A THREAT FOR MAINLY BRIEF HEAVY SHOWERS... An unseasonably strong upper low will move over the islands on Friday, bringing in very unstable air for this time of year. This will be enough for a few heavy showers or thundershowers to develop in some spots. Most of these should be relatively brief, so while widespread flash flooding is unlikely, ponding of water in poor drainage areas, and maybe even some small hail, could occur in a few of the heavier downpours Friday and Friday night.
